Abstract Molecular photoswitches can undergo isomerization under light exposure, making them uniquely attractive for high spatiotemporal resolution remote control of biological functions. Visible and near‐infrared (NIR) light, with their low energy consumption, safety, strong tissue penetration, are particularly suitable applications. Therefore, developing visible‐ NIR light‐driven molecular use is great significance. This review introduces the most common presents state‐of‐art applications in bioimaging, biosensing, drug delivery, photocontrolled cancer phototherapy, photopharmacology. The opportunities challenges future development outlined.

Abstract Azobenzene and its derivatives are the most extensively investigated applied molecular photoswitches, which can undergo reversible transformation between trans cis isomers upon irradiation with light at specific wavelengths. Through structural geometry transformation, property alterations be integrated into smart materials to meet diverse application requirements. Most azo‐based photoswitches require UV for activation. However, complete activation within visible or even near‐infrared range could offer several benefits photoswitch applications, including improved biocompatibility, better penetration, enhanced solar utilization efficiency. This review presents an overview of development visible‐light responsive materials, covering design strategies their applications in energy storage. Recent efforts aimed enhancing performance storage highlighted. According different improving properties, these categorized as those that directly increase isomerization introduce phase transition energy. Furthermore, we discuss challenges opportunities this field a view inspire further exploration.

Abstract Differently substituted pyrrole‐azo–benzene molecular photoswitches were prepared in a straightforward synthetic way. Their fundamental properties investigated by XRD analysis, differential scanning calorimetry, thermogravimetric cyclic voltammetry, UV–Vis absorption spectroscopy, Hyper‐Rayleigh Scattering, and NMR spectroscopy; the experimental results further corroborated DFT calculations. Thermal robustness, HOMO/LUMO levels, altered mostly substituting N –methylpyrrole moiety fine‐tuned modifying benzene substituents. The pyrrole substituent also proved crucial for second‐order non–linear optical (NLO) response as well photoswitching performance. Both fast slow switches can be designed with half–life of ( Z ) –isomer ranging from 48 seconds to 23.28 hours E / molar ratio up 12/88. This comprehensive study allowed elucidation structure‐property relationships subsequently addresses key aspects property tuning via substitution azo‐photoswitches.
